The younger sister of Paul Accola was one of the greatest slalom skiers in the second half of the 1990s. She could win a race at the Ski World Cup ever, but scored two podiums:
- Season 1994 /95 - 2nd place in Park City (USA) behind Vreni Schneider
- Season 1996 /97 - 2nd place in Laax (SUI ) behind Claudia Riegler
At the Olympic Games in Nagano in 1998 she finished in seventh place in the slalom. In March 1998, Martina Accola announced her withdrawal from the race.
